Yeah, it's totally reasonable that they won't have a timeline the day they got the report. And if they fix it the next day, who cares that they didn't give an ETA? Clearly they had better things to do than reporting back.

Well, that depends. CLOCK_MONOTONIC_RAW does avoid NTP slewing, but NTP doesn't just adjust the time scale to adjust for offsets - it also attempts to correct for frequency error in your system clock itself. If you use CLOCK_MONOTONIC_

Not to mention the power supply - what's going to run the pumps when the engines are shut off?

Passenger (and luggage) weight makes a huge difference for fuel burn and overall weight. That said, planes that are above maximum landing weight are generally bound for a very distant destination - on an SEA - LAX leg the plane is almost ce

If they don't use radio technology we'll of course never hear from them - at least not via SETI. So, when it comes to SETI being effective, the interesting case is where the aliens are using radio technology but never advance thei

Except that real ATC can indeed give instructions of that sort. It's not so common for terminal environments to give really long clearances during approach because the pilots may not be ready to copy them down right away, but instructi

You could also use an inherited shared memory segment (an anonymous mmap with MAP_SHARED) to report failure codes. Since you only need to set this up once, it could result in lower overhead than creating pipes for every exec.

Wouldn't it be possible to fool this by forking the blockchain immediately after the first difficulty adjustment after the last remembered block, and then forging timestamps to force the difficulty to go down? You'd need a pretty

It's still a lot of weight to carry around a high-power generator, large-gauge power cables (or heavy transformers and smaller-gauge cables), and four electric motors. This is less of a problem on a train, because the train only has to

IANAL either, but as I read it, if you sue facebook the patent license just goes away. It's essentially the same at that point as if they hadn't mentioned anything at all. So you're either getting something (a conditional lic

Why not just fine the provider that brought the call into the US? They would suddenly have a strong financial incentive to find a way to pass these fines onto the originator.

The upstream minecraft server is a JAR that was run through a Java bytecode obfuscator, which mostly works by renaming all functions and fields with names like that. I'm not aware of any open-source server built with such unreadable na

The problem with this is that mining isn't just about reporting hash rates, it's a critical part of the Byzantine failure tolerant consensus algorithm that was bitcoin's key contribution. If miners had a lower duty cycle as y

No, this is not true, even in digital transmissions. Consider this digital signal: 0000000000 Let's say there's a 1% chance of a bit flipping. But any one of these 10 bits could flip. So for, say, the third bit to flip there'

That would be SIGINT - SIGTERM is sent when you kill the process without specifying a specific signal to send, or when the system is shutting down.

Is it possible that some of the differences shown in this page come from phase changes rather than attenuation? If so, is such a phase change perceptible, even in principle?

Oh, excellent. Once I have JS I'll be able to run Clojure code on it.

UTAU isn't open source - it's freeware. Even redistributing the editor binaries requires permission (as dictated at http://utau2008.web.fc2.com/redistribution.html ). As far as I know there aren't any open sou

UTAU and Vocaloid do indeed use pitch-shifted samples (UTAU even lets you build your own sample libraries). A more recent product, CeVIO, uses modeling IIRC.

There are legitimate uses for temporary base stations - often at large sports events cellular providers will install portable temporary stations for example.

In clojure cond does not have those extra parenthesis - that's a LISPism. cond in clojure works like your example, except that clojure does not have setq. The reason you have those parenthesis on defmacro is that defmacro shares syntax

It is standard procedure for ATC to request altitude (or, more commonly, to get unsolicited altitude reports) on initial contact, and to not trust the Mode C data until it can be cross-checked for exactly this reason.

Non-termination is a fundamental property of turing machines; after all, if all programs terminate, a halting problem decider is trivial to write. While you could certainly argue that the CSS + human system is a turing-complete system, the

Heartbleed doesn't just leak keys. It leaks random bits of memory, which can contain anything - private keys, encrypted data, unencrypted data, whatever happens to pop out. Problem is you can repeat the attack very quickly until the da

The article talks about needing to pull a circuit breaker to kill the transponder - I thought the transponder had a mode selection switch on the pedestal that could be set to standby; is there something else to it that I'm missing?

There have been Linux kernel security bugs where a NULL dereference might not result in a crash, because a malicious user-space program had mapped some accessible memory at address zero. The kernel then went on to skip the optimized-out nul
